I want to meet prospective partners of my hubby's before they have contact with each others' naughty bits.
Hubby wants to meet my prospective partners when he knows they're going to be around for a while (at least 3 dates over the span of about a month and me seeming excited about the person OR consistent dates/talking for about 2 months).
Other people do it differently, like GG said, do what is right for you and yours.
Is there a particular reason she thought she would meet these women when you did? Have you been talking to them together?
